Cooler: Get the Cooler Master Hyper 212 EVO, cheaper for same performance
GPU: I would recommend the MSI Twin Frozr III version of the 570, it has incredible temps and overclocks very well.
Case: Go for the HAF 932 instead of the HAF X. It is $40 cheaper for almost the same case.
SSD: I have read so many bad things about OCZ SSDs, I would highly recommend Crucial M4 for a SSD.
With SLI 570, you need a good 750 watt power supply. If you plan on overclocking your CPU and both graphics cards, I would get an 850 watt just in case. I have the Corsair HX850 and highly recommend it. Corsair and Seasonic are the brands you want to look at, with 80+ Silver as the sweet spot for price/quality.
You will be able to max crysis 2 and bf3 with one 570. I run out of Vram on both of those games, but it is not an issue. I get an average of 36-40 fps in crysis 2 (Dx11 w/ High res textures 1080p) and around 50-60 in the BF3 beta
I would go with the cooler Master Half-X it is big with plenty of room and an amazing amount of cooling options , especially for video cards. For the video card I would go with the Evga because the company stands behind thier lifetime warrenty and I do have experience with that. They also have a step up program which if within 90 days of purchase you want to upgrade you can trade in the one you have for a better one , which in this case you could trade in the 570 for a 580. On the SSD I would go with Corsair, the Force GT is fast and solid. The cpu cooler from Cooler Master is a new model and you want good dependable cooling for your cpu. Antec makes a great dependable power supply and this one will give you enough power for now and later on.
